Description

An intelligent control method for irrigation and drainage equipment

technical field

The invention belongs to the technical field of intelligent drainage and irrigation methods, in particular to a control method of intelligent drainage and irrigation equipment.

Background technique

Existing sprinkler irrigation equipment uses water pumps to pressurize water (or use the drop of high-level water sources) to spray into the air through pipes and sprinklers, disperse into uniform and fine water droplets, and settle on the ground and crops in the form of rain. Compared with irrigation methods through ditches and surface pipes, the use of sprinkler irrigation equipment can provide uniform irrigation, less water loss, and easy automation of irrigation management. This device is especially suitable for gently sloping, undulating, and water-scarce areas. However, this type of sprinkler irrigation equipment uses a unified adjustment method to irrigate the ground at different positions in the same area in a unified way. The degree and water demand are different. Using the same irrigation method not only reduces the accuracy of irrigation, but also has a certain impact on the state of the land, thereby affecting the growth effect of crops, and also causing waste of water resources. Based on the above problems, a more intelligent irrigation equipment is needed to realize targeted irrigation of the land.
